Volume will be the area of the eq triangle times the height.

callisto · Answer

First, find the area of the base
By heron's formula area=sqrt 243
Volume = height x base area = sqrt243 x 7 =  can you do it?

callisto · Answer

Heron's formula:
$$Area \ of \ a \ triangle=\sqrt{s(s-a)(s-b)(s-c)}$$, where s = (a+b+c)/2
a, b, c are the length of the sides of the triangle
